2013 Rocket Ron 29x2.25". Awesome tires! It has a bit more grip, rolls allmost as fast and is as light as the Ralphs. A more versatile tire without any noteworthy penalty: Why not?

Really, take the wider ones. Right now you think you do not need to go that wide, but wide has hardly a penalty, except a little more weight. They roll faster over anything except smooth hardpack or tarmac. Tiny tires only feel fast because they beat the cr*p out of you, because you have to run them at higher pressures to save grip and rims.

Well I need a new set of tires, currently on 2.4F/2.25R Racing Ralph's but I'm looking for a replacement but this time I don't think I need to go that wide so my options are

2013 Rocket Ron 29 x 2.1
2012 Racing Ralph 29 x 2.1

I need a fast rolling tire and looks like new Rocket Ron's are pretty amazing, also they are a tad less than 500grs according to Schwalbe's specs

On the other side Racing Ralph's are pretty amazing and I'm already used to them so, what should I do?

Get both Run the Rocket Ron on the front and the Racing Ralph on the rear. That was the tip from a German colleague who is going to XTerra world championship this year, he's no slouch for giving tips. I got me a set and this is what I'm going to run next. And yes, they were about 500g on a kitchen scale.

I'm looking forward to hearing some ride reports of the new for 2013 Rocket Ron. I am not that impressed with the 2012 variety, but the preview here on MTBR looked like Schwalbe tried to address all the stuff I didn't like. (Squirmy, fragile shoulder knobs, poor cornering grip on loose-over-hardpack.)

Rocket Ron 29" 2.25

Well, my experience with rons, BUT 2011, (Schwalbe Rocket Ron 29 x 2.25
67EPI Kevlar bead / Performance Serie) is, that through the 150 KM I've done on them, I have already twice had a flat tire. Mostly city rides, bit in some mud, but nothing, that should cause the defects I mentioned so often. Some other users report the same problems with Rons, but as I mentioned: mine were the 2011 and performance series - a bit lighter in weight, but therefore with thinner side walls. I also find them not so good for the back wheel, as the side knobs are a bit small and bend in some tight curves, causing the back wheel to wash out a bit. But that is all my own personal opinion. Personally I would opt for tires with bigger knobs and some bit tougher, even if a bit heavier, maybe maxxis ardent or so. The relatively high prices of Schwalbe are also to consider. Happy trails, Fil
